The ultimate in power output and design. Made in Germany metal halide up down wall light. Total Lumen output per lamp is 3,400 lumen's and available in warm white 2,700 kelvin or cool white 4,200 kelvins. Very punchy modern contemporary styled Metal Halide direct / indirect wall light with a good medium to wide beam distribution. Simple installation of the Rox Pro G8.5 via a plug connection in the rear connection box. IP44 for exterior use and smooth lines make this a luminaire that looks smart and is easy to keep clean.

Metal Halide Lamps

Metal halide luminaries are used in many commercial environments due to the high light output and long lamp life. Metal halide lamps do not operate like other lamp sources and need time to reach full output, which can take 5 minutes. They also can not be switched on and of quickly as the lamp needs time to cool down before it can re strike.

Lamp colour ( Kelvins )

The colour of a lamp is defined as a measurement called kelvins. A standard GLS
light bulb in your house would be 2,700 kelvins which is in the warm colour spectrum
and a lamp with 6,000 kelvins would be at the very cold white spectrum. Getting the
right colour temperature of a lamp does matter as the warm colour wavelength helps
to soften skin tones and gives a warm soft relaxed feel and at the other end of the
scale a 4,000 to 6,000 kelvin lamp colour would be used in offices or a fast
food restaurants to make you feel less comfortable and relaxed and more alert. There’s
nothing that can sour your opinion of a compact fluorescent or LED lamp like
buying a 4000K or 5000K bulb when you meant to buy a 2700K bulb, or vice-versa. When
you buy a new, energy efficient bulb, keep your application and colour scheme in mind
and make sure to buy the bulb with a colour temperature to match.

Light output ( Lumens )

The amount of light that is produced by a lamp is called lumens and the more lumens
the lamp has the brighter it will be. Lumens work in conjunction with kelvins and
should not be taken in isolation of each other, for example if you had a very warm
white lamp at 2,700 kelvins and it produced 300 lumens and you then had another lamp
which was a cool white 6,000 kelvins which also produced 300 lumens the cooler lamp
colour would always appear brighter to the naked eye than the warmer one this is
due to the receptors in the eye that react better to a white light spectrum. Another
factor on how bright a light may appear is contrast so if you shine a white 6,000
kelvin light on to a dark wall and a warm 2,700 kelvin lamp on to a white wall the
warmer lamp would appear brighter due to the contrast of the material it is focused
on. So when choosing a lamp always take in to account the area you want to illuminate
and think about Kelvins ( colour ), Lumens ( brightness) and contrast
( colour of area )

All outdoor lighting should be installed by a certified PART P, NIC EIC electrical
contractor to ensure a safe and water tight installation.

Installation

Choosing the style of a product is only part of the equation you must also think
of where that productwill be used and how it will be installed. All exterior lighting
products on our web site have a IP rating which is explained further in our design
ideas section but in simple terms the IP rating is appropriate to each light fitting
and its intended application and is therefore fit for purpose. Water ingress is the
enemy for outdoor lighting and the products supplied are only as good as the installation
as the weakest point is always cable and transformer joints. All joint must be made
100% water tight and this can be done using heat shrink kits, waterproof junction
boxes which are then filled with a resin mix. All joints where possible should be
made above ground for easy access and reduced water ingress. When installing ground
buried lights adequate drainage systems should be put in place especially in clay
based soil areas. If possible use ground surface spike lights rather than a buried
light. Mains 240v cable will haveless joint than a low voltage installation
but care must be taken with the cable runs.
